What are the types of smoke detector?

There are two main types of smoke alarms for home use: ionisation and photoelectric. Photoelectric smoke alarms are usually much faster at detecting smoke from smouldering synthetic material than ionisation alarms.

What is the most common type of smoke detector?

Ionization smoke alarmsIonization smoke alarms are the most common type of smoke alarm and are quicker at sensing flaming, fast moving fires. This type of alarm uses a small amount of radioactive material to ionize air in an internal sensing chamber.

Should smoke detectors be on wall or ceiling?

How many types of fire alarms are there?

four typesThe four types of fire detectors are ionization/photoelectric, photoelectric, ionization, and heat. The differences in these four types are found in how they detect a fire – heat is obviously triggered by temperature while the other three are from smoke.
